CHARLES I. WALKER, OFSACRAMENTQ, CALIFORNIA.

Speqication at l i Application lec September To ayiemit may 'amcerm j .Bent known that CHARLES I. "Amine, a citizen of the Uniteda States, residing at Sacramento, in the county of Sacramento and v /rate .of California, have invented certain-new and useful Improvements in Car- Doors; and I do declare the following to be a full, elear, and exact desoription of the saine, such as will enable others skilled i 'the art to which it Aappeltaillis to make and use the same, referencebeing had to the accompar'gymg drawings,v and tothe characters of reference marked thereon, which-form a part of this application.

, .This invention relates to improvements in railway rolling stock and partlcularly to the co1' doors, the object of the invention being to produce a .car door of either of the types known as outsidecrftlush doors which will be strongly reinforced in all respects, evenly balancer in' position for operation, readily and easily closed and opened and which will be absolutely fire, Water and Weather proof in all respects.

A further object of the invention is to produce a simple and inexpensive door and yetone which is 'exceedingly effective for the pur oses for which it is designed.

T lese objects I accomplish by suchstructure and relative arrangementwof parts as will fully appear by a perusal of the following specification and duim.

In the drawings similar characters of reference indicate corresponding parts in the sererai views. Y

Figure 1 is a sde elevation of a fragmentary portion of a car showing my improved door thereon. Fig. 2 is a horizontal cross section of a flush door and door posts. Fig. 3 is a similar view of an outside door. Fig. 4 is a vertical section of a fragmentary portion of a car showing my improved flush door structure. 'F ig. 5 is a similar view of my improved outside door structure. Fig. 6 is a similar view of an outside door structure but. showing a rnmlifcdforni from that shown .in Fig. 5. Fig. T is a similar view of the door as, applied to steel cars. Fig. 8 is an enlarged sido view of a weather strip and door lock. Fig. 9 is a fragmentary view showing the application of the Weather strip and lock to the car door. Fig. 10 is a sectional vieiv of a fra ientary portion of a door flange and weat er strip.

Referring now more particularly to the characters of reference on the drawings 1n CAB-DOUE.

designates the car and 2 the door openings f" cefor, and 3 the door posts.

Inasmuch as I have herein applied my improved structureto an outside and a flush rately and first the, flush door, (Figs. 2 and 4) In this stnuctnre I provide aroiind the door posts 3 a, metal or other suitable casing 4 having a recess 5 to receive the door when it. is flushed in the usual-manner, and tivo spaced flanges 6 to form a groove 7 to receive a sliding grain door 8. Across the top of the door space is a channel iron guide run-Way 9 in which the door 10 projects and moves in a free manner, the inner side 'of this runway being cnt at the door`hole as at 11 to permit the door to be 'tlushed with the car when closed in the usual manner. At: the bottom of the door space is a metal casting 12 to which is bolted a railway 13 forming an intermediate groove 14-forming a guide for the downwardly projecting flange 15 of a casting 16 on the bottom edge of the door 10. Such casting 16 also has an inwardly projecting flange 17 across the bottom edge of the door 10 and forming a shelf to rest on the tloor 18 of the carwhen the door is flushed thus forming afsupportin rest for such door. 0n the flange 16 are ro. 1ers 19 adapted to support the door upon the tracks 13. The flange 16 forms a bottom brace and support and strengthener for the door 10 and is itself provided with a projecting strengthening rib 20.

The above is the description of the flush door. l will now describe in detail the structure of the outside (loon-(Figs. 1, 3, 5, 8 and 9) viz z--I provide a'top runivay 21 similar to the runway 9 except that it is not; cut out at the door hole as` is the runway 9, the outside door 22 having a bottom flange 2l projecting across the bottom edge of the door and also said casting 23 has a projecting strengthening rib 25. The casting 23 carries rollers 26 moving on an upwardly projecting track 27 on a bottom casting with the` car an intermediate guide slot 29 for the lower edge of the door. For this rounding metal ,casting 30 having project-` ing spaced [langes 31 forming slots 32 to receive a grain door 33. One of said castings ing 28 secured to the ca r, such track 27 formoutside door 22 the door posts 3 have a sur.

30 has a projecting angle iron flange 31 forming a .closure and front stop for the .door I will therefore describe each sepastrengthening casting 23 having a bottom door when closed. The casting on the other post has an inwardly projecting recess 1n which a weather strip and door lockinv flange 36 projects when the door is close This weatner strip and lockfis secured to the door 22 and operated as follows, viz:- On the rear edge of the door 22 is a metal flange or strip 37 rovided with bolts 38 havin a head 39. he strip 36 is provided with inclined slots working over the boltsA 38 and held thereon by the heads 35). Normally the bolts 38 rest in the upper ends aof the slots 40 when the door is open thus holding the strip 86 clear of the recess 35 and of the car, but when the door is closed and is to be locked the strips 36 are lifted on said bolts 38 until the same rest .on said bolts in pockets b ofnsaid slots 40 which holds the strips 36 intothe recess 85, and the same canbe locked in said position by means of passing the usual seal 44 through alined orifices 43 in projecting lugs 41 and ez on the members 36 and 37 respectively which of course locks said member 3` 6 in position in the recess 35. v

Figs.' 6 and 7 show the structure for the doors modified as the came readily could bc for different structures of cars the general structure however being the same, the roller ar bein modified to conform to the botom struc ure of the car. Thus in Fig 6, a castin 44* carries afrail 45 forming an 'interme late' slot 46 in which a projected ange of a U-shaped roller bearing is guided such roller bearing carrying the roller, f 48, and having a flange 49 secured to the# K7 -bottom ofthe door.

In Fig. 7 a steel is shown, the bottom -l edge of the steel door 51, being guided in a slot 52 in a. casting 53 the roller 54 ridin said track and bearing in a yoke 55 secured to the side of the door 51.

From the foregoing description it will be readily seen that I rave produced such a. door structure as substantially fulfils the objects of the invention as herein set forth.

iVhile this specification sets forth in detail the present and preferred construction of the device still in practice such deviations from such detail may be resorted to as do not form a depnrtul'e from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to se cure by Letters Patent. is:

A device as described comprising a' car having door posts a casing disposedaround each post having a door receiving recess, a slotted guide'disposed above the door opening and alon the side of the car and having the inner w of said slot opposite the door opening partly removed, a projectin beam disposed along the bottom of sai opening an upwardly. projecting' railway on said beam forming :,recess between the same and saidcar, a 'Hush closing door, rollers on said door' bearing on said railway, a flange on said door rejecting into said runway, and an inwar ly projecting flan on said door adapted to rest on the car oor when the door isreceived into said recess.

In testinonywhereof I atliir my signature in presence of two witnesses.
